I am having a problem with getting the muzzle flash to look more impressive when the gun is pointing toward the camera.
Here is a screen shot of what it looks like with all the settings shown at the right side. You will have to scroll over to the right to see them. Anyone have any ideas?

I am new at VisionLab and been experimenting with the settings for my footage. Just thanks!

For one thing, you should color grade everything using the "grade object" to even things out.

Right now as it stands, you have the muzzleflash, greenscreen footage and a background that work independently of each other.

You could also have the reflective lighting that comes off the muzzleflash on your subject.

Garrison is right. There's nothing wrong with your muzzleflash. The effect is just incomplete. You'll need to add some reflective lighting in the "shadowed" areas around the "flash." The shot is in daylight so the lighted area will be restricted to the area right around the muzzleflash and will basically light the shadows within that area to complete and "sell" the shot. For example, start with the dark areas around the eyes and other depressed areas in the mask and bounce the flash off them to look as though the muzzleflash is "lighting" those areas every time it "flashes." Just remember, light reflections are dull or flat on dull surfaces like the rubber and they're sharp and crisp, like a mirror, on hard, reflective surfaces like glass and, like all light, the farther from the source it is, the less light there is to reflect.

I was waiting to color grade last.
Nice idea about the light reflecting on the person, this was a test clip to see what I can do with the application.
So I used that day shot so I could see how well the chromakey looked.
At this point in the shot I was hoping to get the flash to have the cross effect (starburst pattern) rather than the round like explosive blob.
Is there a setting I could use to extend the 4 points outward from the center just a bit?

Use the "Side Ejections" amount and enter 4

As Garrison says, setting the side ejections to 4 will give you 4 spiky shapes coning out from the center, then use the Length control for the Side Ejections to control how far out they come from the center.

Alternately, you could start out with a preset that already included side ejections, such as one of the Assault Rifle presets.
